Electrical Engineering QUESTION #2140

Question 1

In Electromagnetic Field Theory, the divergence of a magnetic flux density $\mathbf{B}$ is always zero ($\nabla \cdot \mathbf{B} = 0$). This physically implies:

Magnetic fields are conservative
Isolated magnetic poles (monopoles) do not exist✔️
Magnetic field lines are always straight
The medium is non-magnetic

Correct Answer Explanation

Gauss's Law for Magnetism ($\nabla \cdot \mathbf{B} = 0$) indicates that magnetic flux lines always form closed loops, meaning monopoles do not exist.
